spinloop code

Launch the active harness — one word for spinloop harness open. code takes the same flags, applies a Spinloop the same way, and forwards the same trailing arguments, so it is a shortcut for the launch, not a second command:

spinloop code                            # launch the active harness
spinloop code -O                         # apply ./Spinloop, then launch
spinloop code qwen3.6-27b                # apply the aliased Spinloop, then launch
spinloop code --env prod --prompt "hi"   # configure from prod's deployment, then launch
spinloop code --fleet ./fleet.yaml       # route through a fleet, or its gateway

code is the only way to launch an agent against a fleet: spinloop fleet harness was removed, and typing it names this command instead. A fleet file that names a gateway needs no Spinloop at all — the gateway resolves the model per request — so spinloop code --fleet ./fleet.yaml is a complete launch on a machine holding nothing but the fleet file.

Every flag and argument code accepts is harness open's, so run spinloop harness open --help for the full list, or read that page for the Spinloop, --env, and fleet behaviour in detail.
